That is a 75 lux light, according to this shop, that could have a 95 lux output if you do not add a taillight to the setup too.

However, such figures do not mean a lot. Of all the LED lights I use, I like the Philips SafeRide the best because of its wide beam. I really do not care if a light is a lot brighter many meters in front of me, when in daily use I rather have a light that allows me to judge a sharp corner nearby correctly.
